A flametardo is a double slander of someone who acts both 'Gay' (not in the sexual sense, but more like calling someone a Gaylord'" and Retard as the same time.

John Doe swears that 'The Holiday' is a great movie (He's begin 'Gay' or a 'Flamer') and that Jennifer Aniston is in the movie (He's retarded, because she's not). Therefore John is officially a Flametardo.
